To Jesus everyone was a sinner. Can you show me in scripture when/where the early church accepted unbelievers into its midst?
1 Corinthians 14
22 Tongues, then, are a sign, not for believers but for unbelievers; prophecy,however, is not for unbelievers but for believers.23 So if the whole church comes together and everyone speaks in tongues, and inquirers or unbelievers come in, will they not say that you are out of your mind?24 But if an unbeliever or an inquirer comes in while everyone is prophesying, they are convicted of sin and are brought under judgment by all,
It is within the context of an unbeliever walking in.
